mfd: pcf50633: Remove remaining PCF50633 support

2025-03-14T11:42:51+00:00

Remove the remaining parts of the 50633, the core, headers and glue.

The pcf50633 was used as part of the OpenMoko devices but
the support for its main chip was recently removed in:
commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support")

See https://lore.kernel.org/all/Z8z236h4B5A6Ki3D@gallifrey/

Remove it.

mfd: pcf50633: Remove unused platform IRQ code

2025-03-14T11:42:40+00:00

As part of the pcf50633 removal, take out it's irq code
(which includes one bit still called from the core, but it'll
go soon).

mfd: Remove STA2x11 core driver

2025-03-14T08:59:07+00:00

With commit dcbb01fbb7ae ("x86/pci: Remove old STA2x11 support"), the core
driver for STA2x11 is not needed and cannot be built anymore.

Remove the driver and its header file.

mfd: Add support for AAEON UP board FPGA

2024-12-17T13:17:26+00:00

The UP boards implement some features (pin controller, LEDs) through an
on-board FPGA.

This MFD driver implements the line protocol to communicate with the FPGA
through regmap, and registers pin controller and led cells.

This commit adds support for UP and UP Squared boards.

Based on the work done by Gary Wang .

mfd: Add base driver for qnap-mcu devices

2024-12-17T13:14:33+00:00

These microcontroller units are used in network-attached-storage devices
made by QNAP and provide additional functionality to the system.

This adds the base driver that implements the serial protocol via
serdev and additionally hooks into the poweroff handlers to turn
off the parts of the system not supplied by the general PMIC.

Turning off (at least the TSx33 devices using Rockchip SoCs) consists of
two separate actions. Turning off the MCU alone does not turn off the main
SoC and turning off only the SoC/PMIC does not turn off the hard-drives.
Also if the MCU is not turned off, the system also won't start again until
it is unplugged from power.

So on shutdown the MCU needs to be turned off separately before the
main PMIC.

The protocol spoken by the MCU is sadly not documented, but was
obtained by listening to the chatter on the serial port, as thankfully
the "hal_app" program from QNAPs firmware allows triggering all/most
MCU actions from the command line.

The implementation of how to talk to the serial device got some
inspiration from the rave-sp servdev driver.

Add core MFD driver for the Board Controller found on some Congatec SMARC
module. This Board Controller provides functions like watchdog, GPIO, and
I2C busses.

This commit adds support only for the conga-SA7 module.

mfd: adp5585: Add Analog Devices ADP5585 core support

2024-08-01T13:09:28+00:00

The ADP5585 is a 10/11 input/output port expander with a built in keypad
matrix decoder, programmable logic, reset generator, and PWM generator.
This driver supports the chip by modelling it as an MFD device, with two
child devices for the GPIO and PWM functions.

The driver is derived from an initial implementation from NXP, available
in commit 8059835bee19 ("MLK-25917-1 mfd: adp5585: add ADI adp5585 core
support") in their BSP kernel tree. It has been extensively rewritten.
